Sentry Crash Report:

Description igor 2010-04-14 03:38:07 UTC 
Application that crashed: digikam
Version of the application: 1.1.0
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.31-02063104-generic x86_64
Distribution: Ubuntu 9.10

What I was doing when the application crashed:
i was in the image preview, where there's a row of images across the top and the current image is displayed in the bottom. tag info was open in the right sidebar, and albums view was open in the left sidebar. i had just pushed spacebar to get to the next image, and then i pushed delete to delete that image. this caused a segfault.

 -- Backtrace:

Comment 1 caulier.gilles 2010-04-14 09:03:10 UTC 
Igor, 

please install digikam-debug package to get a full backtrace and post there a new trace.

Alos, use digiKam 1.2.0, the last stable version. Perhaps it fix your problem.

Andi, 

if crash comme from digiKam, sound like a missing QPointer protection for a dialog, somewhere. Right ?

Gilles Caulier
Comment 2 Marcel Wiesweg 2010-04-17 13:52:03 UTC 
Strange backtrace, I have no idea what dialog is started here.
No digikam code visible in thread 1.
Comment 3 caulier.gilles 2010-10-06 09:54:55 UTC 
Igor,

We need more info to hack your problem. Please read comment #1 and #2

Gilles Caulier
Comment 4 caulier.gilles 2010-11-24 09:07:50 UTC 
digiKam 1.6.0 is out:

http://www.digikam.org/drupal/node/550

Please update and check if this entry still valid.

Thanks in advance

Gilles Caulier
Comment 5 Marcel Wiesweg 2011-01-18 14:28:55 UTC 
I assume an upstream problem.
Is it still reproducable with a recent version?
Comment 6 caulier.gilles 2011-07-06 10:49:32 UTC 
We need feedback here...

Gilles Caulier
Comment 7 caulier.gilles 2015-07-03 06:01:07 UTC 
New digiKam 4.11.0 is available.

https://www.digikam.org/node/740

Can you reproduce the problem with this release ?

Gilles Caulier
Comment 8 caulier.gilles 2016-07-09 14:16:44 UTC 
This problem is not reproducible with last 5.0.0.
I close this file now. Don't hesitate to re-open it if necessary.
